Abstract
We present detailed studies on dark-bright vector solitons formed in dispersion- and birefringence-managed fiber lasers sustained by either incoherent or coherent cross-polarization coupling. We show that even under strong influence of the gain bandwidth limitation, coupled dark-bright solitons can still be formed in a fiber laser. Unique features of the dissipative dark-bright vector solitons are studied both numerically and experimentally, and compared with those of the vector solitons formed in nonlinear Schr\odinger equation systems.
